A server runs Windows Server 2008 R2. The Remote Desktop Services server role is installed on the
server. You deploy a new application on the server. The application creates files that have an
extension of .xyz. You need to ensure that users can launch the remote application from their
computers by double- clicking a file that has the .xyz extension. What should you do?

A.
Configure the Remote Desktop Connection Client on the users’ computers to point to the server.

B.
Configure the application as a published application by using a Remote Desktop Program file.

C.
Configure the application as a published application by using a Microsoft Windows Installer
package file.

D.
Configure the application as a published application by using a Remote Desktop Web Access Web
site.

Explanation:
Launching Apps from the Desktop

For users who want to double-click documents to launch the application, terminal services now
provides the ability to “install” the remote application’s link to the desktop. This process effectively
wraps the Remote-App’s RDP file into a Windows Installer package—an MSI file—that is later
installed to desktops in the environment.
At the same time, the installed MSI can modify the file extension associations on the desktop to
reroute a double-clicked file to its associated RemoteApp on the terminal server. Figure 3 shows
how the file extension associations have been modified on a client system after a Word RemoteApp
is installed. Now, double-clicking any of the common Word file extensions will launch Word via the
Remote Desktop Connection.

Figure 3 File extension associations that have been altered to launch the Remote Desktop
Connection To create a Windows Installer package out of an existing RemoteApp, first navigate to
the TS RemoteApp Manager. Right-click the RemoteApp of interest and select Create Windows
Installer Package. By default, all created Windows Installer packages are stored in the location
C:\Program Files\Packaged Programs, but this location can be changed from within the RemoteApp
Wizard. Also configurable within the wizard are the name and port for the server that will host the
RemoteApp, as well as server authentication, certificate settings, and TS Gateway settings.
Settings that relate to the application’s location after installation to a candidate desktop are shown
in Figure 4.

As you can see, it is possible to create a shortcut on the desktop as well as to a location within the
Start menu folder. The most important checkbox on this screen is at the very bottom. It’s the
checkbox for Take over client settings, and it re-associates any file extension associations for the
RemoteApp from the local desktop to the terminal server.
This checkbox must be selected if you want users to be able to double-click documents to launch
their TS-hosted application. Click Next and Finish to complete the wizard.
Please Note: -Since Windows2008R2 Terminal Services (TS) is now rebranded to Remote
Desktop Services (RDS)-
